an214 amplifier problem

Post by leurs on Fri Nov 07, 2014 4:58 pm

May assembled ako na an214 amp na 3 channel,pang bass yung dalawang channel tapos sa tweeter naman yung isa. Bakit kaya mahina yung kabilang channel ng pambass,pagpinihit ko yung volume yung kabila yung unang lalabas ang sound,tapos susunnd naman yung isa. Pero mahina talaga yung kabila nang pang bass. Ano kaya ang sira nito? Thanks in advnce po.

may balance control ka ba? pag wla... try mo muna pagpalitin ang mga sound ic.. pag lumipat ang mahina ay may problem ang ic an214.. pero pag wlang nabago ay suyurin mo ngayon ang mga peripheral parts ng sound ic "an214" na nakapaligid sa kanya... kong kayo ang gumawa ng pcb.. ay double visual check na rin baka may naputol o loose connection.

Wala papo tung balance control. At tsaka di po ako gumawa,pina assemble ko lang. Akala ko nuong una potentiometer nya lang ang sira kasi medjo scratch2 na tunog pag pinihit ko,so nung napalitan ko na,yung scratch2 na tunog lang ang nawala yung balanse ng tunog nya,ganun parin mahina ang sa kabilang channel. Pwede ko rin ba lagyan nalang nang balance control para maging balance na silang dalawa? Wala bang masisira,para matapos nato? Thanks again mga sir atsaka sir ultrasonic

@sir Ultrasonic: Mayroon na nga itong built in tone control. Pag lalagyan ko to ng balance duon po ba sa input ng tone control ang potentiometer?

@sir Arkin: Tama rin po kayo sir,nakaparallel yung pang tweeter nito sa mahinang side na ampli. Try ko nga gawin yang sinasabi mong mylar na .1mf na value feedback nalang ako dito,salamat po ulit sa inyong dalawa.

Napansin ko magkaiba templada yung bass niya. Sa kabila,yung malakas wala masyadong kanta,tapos sa kabila yung mahina,may kanta siya,tsaka mahina lang ang bass niya. Balak ko gawan ng 2 pang channel na booster para maging 4 channel ang booster. Yung 1 channel ng amp connect ko sa dalawang channel na booster tapos yung 1 channel naman na mahina,connect din sa 2 channel na booster.
